[0006] In self-refraction using such a subjective optometry device, the examination is performed according to a self-refraction program that takes into account the examination conditions for smoothly conducting the self-refraction. However, there are various conditions for the examination of the eye to be examined (for example, the experience of the examiner, the optical characteristics of the eye to be examined, etc.), the facilities where the device is installed, and the operating conditions of the store (for example, the congestion situation, the examination schedule, etc.), and sometimes the pre-set self-refraction program is not suitable.

[0007] In view of the above-mentioned problems, the present disclosure aims to provide a subjective optometry system and a subjective optometry program that can easily execute a self-optology program suitable for a situation in which self-optology is performed on a subject's eye.

[0029] <Summary>

[0030] The outline of the subjective optometry system of the present embodiment will be described. It should be noted that the following items classified by <> can be used independently or in association with each other.

[0031] The subjective optometry system of this embodiment is a system for measuring the optical characteristics of the eye to be examined in a subjective manner. For example, the optical characteristics of the eye to be examined may be eye refractive power (for example, at least one of spherical power, cylindrical power, astigmatism axis angle, etc.), binocular vision function (for example, at least one of prism amount, stereoscopic vision function, etc.), contrast sensitivity, etc.

[0032] The subjective optometry system of this embodiment may include an optotype presenting unit (eg, 31). The optotype presenting unit presents an inspection optotype to the eye to be inspected. For example, the optotype presenting unit presents an inspection optotype to the eye to be inspected by emitting an optotype light beam toward the eye to be inspected.

[0033] For example, the sight mark light beam from the sight mark presenting unit can be directly guided toward the eye to be inspected. In addition, for example, the sight mark light beam from the sight mark presenting unit can also be guided toward the eye to be inspected via a light projection optical system (for example, the light projection optical system 30). For example, the light projection optical system can have at least one optical component for the sight mark light beam emitted from the sight mark presenting unit to pass through. As an example, it can have at least any one of a lens, a reflector, etc.

[0034] The subjective optometry system of this embodiment may include a correction unit. The correction unit changes the optical characteristics of the sight mark light beam emitted from the sight mark presenting unit. For example, the correction unit may be arranged in the optical path of the light projection optical system and changes the optical characteristics of the sight mark light beam.

[0035] The correction unit may be any structure as long as it can change the optical characteristics of the sight mark beam.

[0036] For example, the correction unit may include an optical element. For example, the optical element may be at least one of a spherical lens, a cylindrical lens, a variable focus lens, a cross cylindrical lens, a rotating prism, a wavefront modulation element, etc. Of course, the optical element may also be different from them. In this case, the optical characteristics of the sight mark beam are changed by controlling the optical element.

[0037] In addition, for example, the correction unit may also have a structure for optically changing the presentation position (presentation distance) of the sight mark relative to the eye to be examined. As an example, it may have a structure for moving the sight mark presentation unit in the optical axis direction, or it may have a structure for moving an optical element (e.g., a spherical lens, etc.) in the optical path in the optical axis direction. In this case, the optical characteristics of the sight mark beam are changed by controlling a driving unit for controlling at least one of the sight mark presentation unit and the optical element.

[0038] In addition, for example, the correction unit may be an eye refractive power measuring unit (e.g., eye refractive power measuring unit 40) that switches the arrangement of an optical element (e.g., optical element 52) ​​in front of the eye to be inspected via an inspection window (e.g., inspection window 43). For example, the eye refractive power measuring unit may have a lens disk (e.g., lens disk 50) in which a plurality of optical elements are arranged on the same circumference. In this case, the optical characteristics of the sight mark beam are changed by controlling a driving unit (e.g., driving unit 51, driving unit 53, etc.) for controlling the lens disk.

[0039] The subjective optometry system of this embodiment may include a self-optometry program setting unit (e.g., control unit 60). The self-optometry program setting unit sets either a first self-optometry program or a second self-optometry program, wherein the first self-optometry program automatically performs a plurality of inspection items on the subject's eye based on the answer input by the subject, and the second self-optometry program automatically performs a plurality of inspection items on the subject's eye based on the answer input by the subject, and the inspection conditions are different from those of the first self-optometry program. For example, the inspection item may be an item indicating the type of inspection performed in the subjective inspection of the subject's eye. For example, it may be an item set for each type of optical characteristics of the subject's eye and an item for obtaining inspection results of prescribed optical characteristics of the subject's eye.

[0040] It should be noted that the subjective optometry system may include a selection unit for selecting and setting a self-optometry program. For example, the selection unit may be a structure capable of selecting any one of the first self-optometry program and the second self-optometry program. As an example, it may be at least one of a check button, a radio button, a drop-down menu, a selection switch provided on the device housing, etc. Thus, the examiner can set any self-optometry program.

[0041] For example, in this embodiment, the difference in the inspection conditions in the first self-optometry program and the second self-optometry program may be at least one of the difference in conditions related to the inspection items, the difference in conditions related to the inspection sight mark, etc. Of course, it may also be a different combination of conditions related to the inspection items and the inspection sight mark.

[0042] For example, in the first self-optology procedure and the second self-optology procedure, the difference in conditions related to the examination items may be a difference in at least any one of the examination items implemented in each self-optology procedure, the order in which multiple examination items are implemented, the parameters used to determine the examination results in the specified examination items (for example, the maximum visual acuity value of the eye to be examined, etc.), etc.

[0043] For example, it is also possible that the multiple inspection items are different in the first self-optometrist program and the second self-optometrist program. That is, it is also possible that the combination of the multiple inspection items included in the first self-optometrist program and the second self-optometrist program is different. For example, it is also possible that the multiple inspection items included in the first self-optometrist program and the multiple inspection items included in the second self-optometrist program are all different. In addition, for example, it is also possible that at least one of the multiple inspection items included in the first self-optometrist program and the multiple inspection items included in the second self-optometrist program is the same. As an example, in this case, the multiple inspection items in the second self-optometrist program can be set in a manner that includes inspection items different from the multiple inspection items included in the first self-optometrist program. Thus, it is easy to set a self-optometrist program corresponding to the type of glasses desired by the examinee, the inspection condition of the examinee's eye (for example, the experience of the examinee, the optical characteristics of the examinee's eye, etc.), the facility where the subjective optometrist system is set, the operating conditions of the store (for example, crowded time periods, schedules, etc.), etc., and perform each inspection item.

[0044] In addition, for example, the difference in conditions related to the test sight mark in the first self-optometry program and the second self-optometry program may be a difference in at least any one of the number of test sight marks used in the test items included in each self-optometry program, the type of test sight mark (for example, Landau ring sight mark and rolling E sight mark, etc.), the representation form of the visual acuity value of the test sight mark (for example, decimal representation and logarithmic representation, etc.), etc. It should be noted that the difference in the test conditions in the first self-optometry program and the second self-optometry program may also include the difference in the content of the voice guidance accompanying the difference in the conditions related to the test items and the test sight marks, etc.

[0045] For example, the inspection sight marks used in the inspection items in the first self-optology program and the second self-optology program may be different. That is to say, the inspection sight marks used in the inspection items shared by the first self-optology program and the second self-optology program may be different. For example, in the inspection of the subject's eye, the type of inspection sight marks and the form of visual acuity value may be changed in accordance with the country or region where the subjective optometry system is set up, or the number and type of inspection sight marks may be changed according to the inspection condition of the subject's eye. By pre-setting a plurality of self-optology programs with different inspection sight marks as in the present embodiment, it is possible to switch the self-optology programs as needed and conduct the inspection smoothly.

[0046] In this embodiment, the multiple examination items included in each personal optometry program may include examination items for checking the vision of the eye to be examined. As an example, it may be a naked eye vision test for checking the naked eye vision of the eye to be examined, a corrected vision test for checking the corrected vision of the eye to be examined, and the like.

[0047] In addition, in this embodiment, the multiple examination items included in each individual optometry program may also include examination items for examining the refractive power of the eye to be examined. As an example, it may include at least any one of a spherical examination for examining the spherical refractive power of the eye to be examined, a cylindrical examination for examining the cylindrical refractive power of the eye to be examined, and an astigmatism axis examination for examining the astigmatism axis angle of the eye to be examined. Of course, it may also include all of the spherical examination, the cylindrical examination, and the astigmatism axis examination.

[0048] In addition, in the present embodiment, the plurality of examination items included in each self-refraction program may also include examination items for checking the binocular vision function of the eye to be examined. As an example, it may include at least any one of a binocular accommodation balance check for checking the balance of the accommodation of the eye to be examined, a slant position check for checking the slant position of the eye to be examined, a strabismus check for checking the strabismus of the eye to be examined, a convergence check for checking the convergence of the eye to be examined, a fusion check for checking the fusion of the eye to be examined, and a stereoscopic vision check for checking the stereoscopic vision of the eye to be examined. Of course, it may also include all of the binocular accommodation balance check, slant position check, strabismus check, convergence check, fusion check, and stereoscopic vision check.

[0049] It should be noted that the multiple examination items included in each personal optometry program may also be a combination of at least any one of examination items for examining the visual acuity of the eye to be examined, examination items for examining the refractive power of the eye to be examined, examination items for examining the binocular vision function of the eye to be examined, etc. Of course, all of these examination items may also be included.

[0050] In this embodiment, the first self-optology program may include an inspection item for checking the refractive power of the eye to be inspected as a plurality of inspection items, and the second self-optology program may include an inspection item for checking the binocular vision function of the eye to be inspected as a plurality of inspection items in addition to the inspection item for checking the refractive power of the eye to be inspected. For example, the inspection item for checking the refractive power of the eye to be inspected is a general inspection item. For example, when making glasses for the eye to be inspected, the inspection item for checking the refractive power is performed. Therefore, by setting the first self-optology program, more subjects can be efficiently dealt with. In addition, for example, the inspection item for checking the binocular vision function of the eye to be inspected is an inspection item that is performed in situations where one wants to understand the optical characteristics of the eye to be inspected. Therefore, by setting the second self-optology program, the inspection results of the refractive power and visual function of the eye to be inspected can be used to make glasses that are more suitable for the eye to be inspected.

[0051] The subjective optometry system of this embodiment may include a control unit (e.g., control unit 60). The control unit controls at least one of the sight mark presentation unit and the correction unit based on the first self-optometry program or the second self-optometry program set by the self-optometry program setting unit, so that optometry according to the process of the first self-optometry program or the second self-optometry program is performed. For example, the control unit may control the sight mark presentation unit based on the first self-optometry program or the second self-optometry program, and change at least one of the type of inspection sight mark displayed on the sight mark presentation unit, the visual acuity value of the inspection sight mark, etc. In addition, for example, the control unit may also control the correction unit based on the first self-optometry program or the second self-optometry program, and change at least one of the correction degree of the eye to be inspected, the configuration of the optical element, etc. As a result, the inspection can be smoothly performed according to the program selected in accordance with the type of glasses desired by the examinee, the inspection condition of the eye to be inspected, the facility where the subjective optometry system is installed, the operating conditions of the store, etc.

[0052] The subjective optometry system of the present embodiment may include a setting change unit (e.g., the control unit 60). For example, the setting change unit changes at least any one of the inspection conditions of the first self-optometry program and the inspection conditions of the second self-optometry program. That is, for example, by using the setting change unit, at least any one of the inspection conditions of the first self-optometry program and the inspection conditions of the second self-optometry program can be customized. For example, for the initial inspection condition (first inspection condition) in the first self-optometry program and the initial inspection condition (second inspection condition) in the second self-optometry program, the setting change unit may be configured to be able to change only the first inspection condition, or may be configured to be able to change only the second inspection condition. Of course, for example, the setting change unit may also be configured to be able to change all of the first inspection condition and the second inspection condition. For example, for the subject, sometimes the inspection conditions of the first self-optometry program and the second self-optometry program pre-set in the subjective optometry system are not suitable, therefore, by using the setting change unit to change the inspection conditions, the inspection can be smoothly carried out under the desired inspection conditions.

[0053] The subjective optometry system of this embodiment may include an optometry plan setting unit (e.g., control unit 60). The optometry plan setting unit sets the first self-optometry program and the second self-optometry program to establish corresponding optometry plans relative to a specified period. For example, the specified period may be a regular period such as a specified date, a specified time (e.g., morning and afternoon, a time period specified by the inspector, etc.). In addition, for example, the specified period may also be a regular period based on calendar information such as a day of the week, a week, or a month. Thus, an optometry plan corresponding to the operating conditions of the facility or store where the subjective optometry system is installed can be set. It should be noted that, for example, in such a case, the aforementioned self-optometry program setting unit switches and sets the first self-optometry program and the second self-optometry program based on the optometry plan set by the optometry plan setting unit. Since each self-optometry program is automatically switched at specified periods, the inspection can be carried out smoothly.

[0054] The subjective optometry system of this embodiment may include an operation unit (e.g., an examiner controller 10). The operation unit inputs an operation signal for setting at least one of the first self-optometry program and the second self-optometry program. In this case, the optometry plan setting unit sets the first self-optometry program and the second self-optometry program to establish a corresponding optometry plan for a specified period based on the operation signal from the operation unit. Thus, for example, managers of facilities and stores that set up the subjective optometry system or examiners who use the subjective optometry system can set the most suitable optometry plan for each facility or store.

[0055] Of course, for example, the operation signal for setting the optometry plan can also be input by receiving the operation signal from the management medium (for example, a computer, etc.) that manages the subjective optometry system. In addition, for example, the operation signal for setting the optometry plan can also be input by using an external storage unit (for example, an SD card, a USB memory, a server, a cloud, etc.). In this case, the setting of the optometry plan stored in the external storage unit can be read by the control unit of the subjective optometry system to input the operation signal corresponding to the setting. For example, when using such a management medium and an external storage unit, in facilities and stores that have introduced the subjective optometry system, it is also possible to easily unify the contents of the first self-optometry program and the second self-optometry program, the contents of the optometry plan, etc.

[0056] It should be noted that the present disclosure is not limited to the devices described in this embodiment. For example, terminal control software (program) that performs the functions of the above-mentioned embodiment can also be supplied to the system or device via a network or various storage media, and the control device (e.g., CPU, etc.) of the system or device reads and executes the program.

[0057] <First Embodiment>

[0058] A first embodiment of the subjective optometry system of the present embodiment is described. In this embodiment, as a subjective optometry system, a subjective optometry device for subjectively measuring the optical characteristics of the eye to be examined is illustrated, which is integrally provided with a display for displaying a test sight mark to the eye to be examined and an eye refractive power measuring unit for changing the optical characteristics of the sight mark light beam emitted from the display. Of course, for example, the display may also be provided as a housing independent of the subjective optometry device.

[0059] <Device Appearance>

[0060] Figure 1A and Figure 1B 2 is an external view of the subjective optometry device 100 . Figure 1A This is a state where the eye refractive power measurement unit 40 is supported at the standby position. Figure 1B For example, the subjective optometry device 100 includes a housing 1, a presentation window 2, a speaker 3, a holding unit 4, an examiner controller 10, a subject controller 20, an eye refractive power measurement unit 40, and the like.

[0061] The housing 1 has a light projection optical system 30 inside. The presentation window 2 allows the sight mark beam generated by the light projection optical system 30 to pass through. The sight mark beam is projected to the subject's eye E through the presentation window 2. It should be noted that when an eye refractive power measuring unit 40 is arranged between the subject's eye E and the presentation window 2 (see Figure 1B ), a sight mark beam is projected to the subject's eye E via the presentation window 2 and the inspection window 43 described later. Thus, the inspection sight mark is presented to the subject's eye E. The speaker 3 outputs voice guidance and the like.

[0062] The holding unit 4 holds the eye refractive power measurement unit 40. For example, the holding unit 4 moves the arm by driving a driving unit (motor, etc.) (not shown) to move the eye refractive power measurement unit 40 connected to the arm. Thus, the standby position and the measurement position of the eye refractive power measurement unit 40 are switched.

[0063] The examiner controller 10 is used for the examiner to operate the subjective optometry device 100. The examiner controller 10 includes a switch unit 11, a monitor 12, and the like. The switch unit 11 inputs signals for making various settings (for example, movement of the eye refractive power measurement unit 40, etc.). The monitor 12 displays a self-optology assistance screen described later. For example, various information (for example, examination results of the subject's eye E, etc.) can be displayed on the self-optology assistance screen. It should be noted that the monitor 12 can also function as a touch panel that also serves as the switch unit 11. The signal from the examiner controller 10 is output to the control unit 60 via wired communication or wireless communication.

[0064] The subject controller 20 is used to input the subject's answer. The subject controller 20 includes an answer lever 21, an answer button 22, etc. The answer lever 21 is used when the subject inputs a direction relative to the inspection sight mark. For example, the signal of the four directions of up, down, left, and right can be input by tilting operation. The answer button 22 is used when the subject does not select a direction relative to the inspection sight mark. The signal from the subject controller 20 is output to the control unit 60 via wired communication or wireless communication.

[0065] <Light projection optical system>

[0066] Figure 2A and Figure 2B It is a schematic diagram of the light projection optical system 30 . Figure 2A Shows the optical configuration for distance vision testing. Figure 2B The optical arrangement for near vision inspection is shown. The light projection optical system 30 projects a sight target beam toward the subject's eye E. For example, the light projection optical system 30 includes a display 31, a plane reflection mirror 32, a concave reflection mirror 33, a near-far switching unit 34, and the like.

[0067] The display 31 displays an optotype (e.g., a fixation optotype, a test optotype, etc.). The optotype light beam emitted from the display 31 is imaged on the fundus of the eye E to be inspected, thereby presenting the optotype to the eye E to be inspected. For example, the display 31 may be an LCD (Liquid Crystal Display), an organic EL (Electro Luminescence), a plasma display, etc.

[0068] The display 31 may also include a polarizing optical component. For example, the polarizing optical component may be disposed on the front surface of the display 31, or the polarizing optical component may be integrated into the display 31. Thus, the display 31 can emit linear polarized light having a polarization axis in a predetermined direction (vertical direction, horizontal direction, or 45-degree oblique direction, etc.). In this embodiment, the display 31 emits linear polarized light having a vertical polarization axis ( Figure 3 The sight mark beam has a polarization axis as shown by arrow 50Y.

[0069] Figure 3: is a diagram showing the polarizing optical member 15. For example, the polarizing optical member 15 has a left-eye optical region 57L and a right-eye optical region 59R alternately arranged in a linear or lattice shape on the front surface of the display 31. In the pixel P of the display 31, the left-eye optical region 57L is arranged to correspond to the first pixel region A1 of at least two adjacent pixels, and the right-eye optical region 59R is arranged to correspond to the second pixel region A2 of at least two adjacent pixels. In the present embodiment, the left-eye optical region 57L and the right-eye optical region 59R are alternately arranged to be adjacent in a horizontal line shape having a width of two pixels of the display 31. In addition, in the present embodiment, the left-eye optical region 57L and the right-eye optical region 59R coincide with (substantially coincide with) the horizontal line-shaped pixel region A (pixel regions A1 and A2) having a width of two pixels in the display 31.

[0070] The polarizing optical member 15 converts the sight mark beam emitted from the display 31 and passing through the left-eye optical region 57L and the sight mark beam emitted from the display 31 and passing through the right-eye optical region 59R into sight mark beams having polarization axes orthogonal to each other. For example, in the present embodiment, the sight mark beam emitted from the display 31 and passing through the left-eye optical region 57L is converted into linear polarization having a polarization axis in a direction of 45 degrees, and the sight mark beam emitted from the display 31 and passing through the right-eye optical region 59R is converted into linear polarization having a polarization axis in a direction of 135 degrees.

[0071] For example, the polarizing lenses 54L and 54R described later in the eye refractive power measurement unit 40 have polarization axes of 45 degrees and 135 degrees, respectively. Therefore, when the eye to be examined observes the sight mark through the polarizing lenses 54L and 54R, only the sight mark light beam from the left eye optical region 57L passes through the polarizing lens 54L to reach the left eye, and only the sight mark light beam from the right eye optical region 59R passes through the polarizing lens 54R to reach the right eye. Thus, the inspection sight mark can be separated in the left eye and the right eye, and different inspection sight marks can be presented to the left eye and the right eye.

[0072] The plane mirror 32 reflects the sight mark beam from the display 31 and guides it to the concave mirror 33. In addition, the plane mirror 32 reflects the sight mark beam from the display 31 and guides it to the eye to be inspected E. For example, in the near vision test of the eye to be inspected E, the plane mirror 32 is arranged so that the distance (presentation distance) from the eye to be inspected E to the display 31 is optically 40 cm. It should be noted that a reflecting member such as a prism, a beam splitter, or a half mirror can be used instead of the plane mirror 32.

[0073] The concave reflector 33 reflects the sight mark beam from the display 31 and guides it to the plane reflector 32. For example, in the far vision test of the eye E to be examined, the concave reflector 33 is arranged so that the distance (presentation distance) from the eye E to be examined to the display 31 is optically 5 m. It should be noted that a reflective member such as an aspherical reflector or a free-form surface reflector can be used instead of the concave reflector 33. In addition, a lens or the like can be used instead of the concave reflector 33.

[0074] The near-far switching unit 34 switches the configuration of the display 31 during the distance vision test and the near vision test of the subject's eye E. For example, the near-far switching unit 34 drives a driving unit (motor, etc.) (not shown) to move the holding unit, thereby moving the display 31 held by the holding unit. Thus, the distance vision configuration and the near vision configuration of the display 31 are switched.

[0075] For example, during the distance vision test of the subject's eye E, the display screen of the display 31 faces the back side of the housing 1 (see FIG. Figure 2A ). The sight mark beam from the display 31 passes through the optical axis L1 and enters the plane reflector 32, and is reflected by the plane reflector 32 in the direction of the optical axis L2. In addition, it passes through the optical axis L2 and enters the concave reflector 33, and is reflected by the concave reflector 33 in the direction of the optical axis L3. In addition, it passes through the optical axis L3 and enters the plane reflector 32, and is reflected by the plane reflector 32 in the direction of the optical axis L4. Thus, the sight mark beam is projected onto the subject's eye E inside the housing 1 and is emitted to the outside of the housing 1 via each optical component.

[0076] For example, during the near vision test of the subject's eye E, the display screen of the display 31 is directed toward the upper surface of the housing 1 (see FIG. Figure 2B The sight mark beam from the display 31 passes through the optical axis L3 and enters the plane reflector 32, and is reflected by the plane reflector 32 in the direction of the optical axis L4. Thus, the sight mark beam is projected onto the subject's eye E inside the housing 1 and then emitted to the outside of the housing 1 via each optical component.

[0077] <Eye refractive power measurement unit (corrective optical system)>

[0078] Figure 4 1 is a schematic diagram of an eye refractive power measuring unit 40. The eye refractive power measuring unit 40 measures the refractive power of the subject's eye E in a subjective manner. In addition, the eye refractive power measuring unit 40 is used as a corrective optical system. The corrective optical system is arranged in the optical path of the projection optical system 30, and changes the optical characteristics of the sight mark beam. For example, the eye refractive power measuring unit 40 includes a forehead rest 41, a lens unit 42, an inspection window 43, a moving unit 44, and the like.

[0079] The forehead rest 41 is fixed to the eye E to be examined at a predetermined examination position by abutting the head of the examinee, and the distance from the eye E to the examination window 43 is kept constant. The lens unit 42 has a left lens unit 42L and a right lens unit 42R, which are a pair of left and right lenses. The lens unit 42 has an examination window 43 (a left examination window 43L and a right examination window 43R).

[0080] The moving unit 44 adjusts the interval between the left lens unit 42L and the right lens unit 42R and the convergence angle (convergence angle) of the left lens unit 42L and the right lens unit 42R. For example, the moving unit 44 adjusts the interval between the left lens unit 42L and the right lens unit 42R by driving the driving unit 45 (the left driving unit 45L and the right driving unit 45R). In addition, for example, the moving unit 44 adjusts the convergence angle of the left lens unit 42L and the right lens unit 42R by driving the driving unit 46. It should be noted that, for the detailed structure of the moving unit 44, please refer to Japanese Patent Publication No. 2004-329345, for example.

[0081] The lens unit 42 has a lens disk 50 inside. The lens disk 50 has a pair of left and right lens disks 50L and right lens disks 50R. The lens disk 50 is rotated by the drive of the drive unit 51 (left drive unit 51L and right drive unit 51R). In addition, the lens disk 50 arranges the opening (or lens of 0D) and a plurality of optical elements 52 (left optical element 52L and right optical element 52R) on the same circumference. These optical elements are rotated by the drive of the drive unit 53 (left drive unit 53L and right drive unit 53R). As a result, the desired optical element 52 is switched and arranged on the inspection window 43 at a desired angle.

[0082] The lens disk 50 is composed of one lens disk or a plurality of lens disks. For example, a spherical lens disk, a cylindrical lens disk, an auxiliary lens disk, etc. may be provided. As an example, the spherical lens disk may have a plurality of spherical lenses with different spherical degrees (spherical refractive powers). In addition, as an example, the cylindrical lens disk may have a plurality of cylindrical lenses with different cylindrical degrees (cylindrical refractive powers). In addition, as an example, the auxiliary lens disk may have a shielding plate, a polarizing lens (polarizing lenses 54L and 54R), a red filter / green filter, a dispersion prism, a Maddox rod lens, a rotating prism, a cross cylindrical lens, an automatic cross cylindrical lens, an alignment lens, etc. The drive unit 51 and the drive unit 53 may also be provided for each lens disk.

[0083] It should be noted that the eye refractive power measuring unit 40 only needs to be able to change the optical characteristics of the sight mark beam. For example, it can be a structure that controls an optical element as in the present embodiment. In addition, for example, it can also be a structure that controls a wavefront modulation element.

[0084] <Control Unit>

[0085] Figure 5 This is a schematic diagram of the control system of the subjective optometry device 100. For example, the control unit 60 includes a CPU (processor), RAM, ROM, etc. For example, the CPU controls the various components in the subjective optometry device 100. For example, the RAM temporarily stores various information. For example, the ROM stores various programs for controlling the operation of the subjective optometry device 100, inspection target data, etc. It should be noted that the control unit 60 may also be composed of a plurality of control units (that is, a plurality of processors).

[0086] The control unit 60 is connected to the speaker 3, the display 31, the controller 10 for the examiner, the controller 20 for the subject, a nonvolatile memory 70 (hereinafter referred to as the memory 70), etc. In addition, the control unit 60 is connected to the drive unit of the holding unit 4, the drive unit of the near-far switching unit 34, the drive unit of the eye refractive power measurement unit 40 (drive units 45, 46, 51, 53), etc.

[0087] The memory 70 is a non-temporary storage medium that can retain stored content even when power supply is cut off. For example, a hard disk drive, a flash ROM, a USB memory, etc. can be used as the memory 70.

[0088] <Control Action>

[0089] The control operation in the first embodiment of the subjective optometry device 100 having the above-described structure will be described.

[0090] The subjective optometry device 100 of this embodiment can set two self-optology programs for automatically performing a plurality of examination items on the subject's eye based on the answers input by the subject. For example, the two self-optology programs have different combinations of a plurality of examination items.

[0091] For example, a self-optometer program (hereinafter referred to as the first self-optometer program) is a program that includes inspection items for checking the refractive power of the eye to be inspected as multiple inspection items. For example, the inspection items for checking the refractive power of the eye to be inspected are general inspection items. As an example, it is performed when making glasses. For example, another self-optometer program (second self-optometer program) is a program that includes inspection items for checking the binocular vision function of the eye to be inspected in addition to the inspection items for checking the refractive power of the eye to be inspected. For example, the inspection items for checking the binocular vision function of the eye to be inspected are inspection items that are performed when one wants to understand the optical characteristics of the eye to be inspected. These first self-optometer program and the second self-optometer program are pre-stored in the memory 70.

[0092] In addition, the subjective optometry device 100 of the present embodiment is initially set with a first self-optometry program, so that the subjective examination according to the process of the first self-optometry program is performed. However, for example, the first self-optometry program and the second self-optometry program can be switched and set appropriately according to the type of glasses desired by the examinee, the examination conditions of the examinee's eye (for example, the examinee's experience, the optical characteristics of the examinee's eye, etc.), the facility where the subjective optometry system is installed, the operation conditions of the store (for example, the crowded time period, the schedule, etc.), etc.

[0093] <Subjective examination based on the first self-refraction procedure>

[0094] The following describes the subjective inspection according to the process of the first self-optometry procedure. The examiner uses the self-optometry assistance screen displayed on the monitor 12 of the examiner controller 10 to prepare for the subjective inspection according to the process of the first self-optometry procedure, input a start signal, initialize the inspection results, etc.

[0095] Figure 6 This is an example of the self-eye test assistance screen 200 when the first self-eye test program is set. For example, the self-eye test assistance screen 200 includes an operation image area 210, an eye test program setting area 220, and the like.

[0096] An operation image including information about the optical characteristics of the sight mark light beam emitted from the display 31 toward the eye to be inspected is displayed in the operation image area 210. For example, in the operation image, a value related to the optical characteristics of the sight mark light beam is displayed for each type of optical characteristics. The examiner can indicate the values ​​of multiple types of optical characteristics (spherical power, cylindrical power, astigmatism axis angle, etc.) by operating various buttons and values ​​on the operation image area 210 via the touch panel or the switch unit 11. It should be noted that if self-refraction is performed appropriately, the correction value of the optical characteristic displayed in the operation image becomes the measured value of the optical characteristic of the eye to be inspected.

[0097] The optometry program setting area 220 is provided with an ID button 221, an initial value input button 222, a near measurement selection button 223, a self-optometry program switching button 224, a voice guidance selection button 225, a volume test button 226, and a start button 227. For example, the ID button 221 is a button for inputting the ID of the subject. For example, the initial value input button 222 is a button for obtaining the initial correction value (initial value) when the self-optometry of the subject's eye starts. As an example, the initial value can be the other-eye refractive power of the subject's eye measured by the other-eye refractive power measuring device, the lens information of the glasses measured by the glasses lens measuring device, etc. For example, the near measurement selection button 223 is a button for selecting whether to perform near measurement in the subjective examination. For example, the self-optometry program switching button 224 is a button for switching between the first self-optometry program and the second self-optometry program. It should be noted that the name of the self-optometry program currently selected is displayed overlappingly on the self-optometry program switching button 224. For example, the voice guidance selection button 225 is a button for changing the language of the voice guidance. For example, the volume test button 226 is a button for playing a test voice for confirming the volume of the voice guidance. For example, the start button 227 is a button for starting self-refraction.

[0098] <Setting of initial values>

[0099] First, the examiner obtains the alien eye refractive power of the subject's eye in order to correct the subject's eye with a prescribed correction value (initial value). For example, after the examiner uses the ID button 221 to input the subject's ID, he presses the initial value input button 222. For example, based on the input signal from the initial value input button 222, the control unit 60 outputs an operation signal to the alien eye refractive power measurement device (not shown) to cause it to send the alien eye refractive power corresponding to the subject's ID. For example, if the alien eye refractive power measurement device receives the subject's ID from the subjective optometry device 100, it calls out the alien eye refractive power corresponding to the subject's ID from the memory and sends it to the subjective optometry device 100. The control unit 60 of the subjective optometry device 100 receives the alien eye refractive power sent from the alien eye refractive power measurement device. In this way, the alien eye refractive power of the subject can be obtained.

[0100] For example, the control unit 60 sets the refractive power of the other eye as the initial value of the subjective examination. For example, the control unit 60 controls the eye refractive power measurement unit 40 to arrange the optical element 52 having a predetermined spherical power and the optical element 52 having a cylindrical power in the inspection window 43. In addition, for example, the control unit 60 arranges the optical element 52 having a predetermined cylindrical power in the inspection window 43 at a predetermined astigmatism axis angle. Thus, the subject's eye E is corrected at the initial value.

[0101] <Subjective inspection>

[0102] After the examiner corrects the subject's eye E using the initial value, he confirms the self-optology program switching button 224 on the self-optology auxiliary screen 200, confirms the currently set self-optology program, and presses the start button 227. The control unit 60 starts the self-optology for the subject's eye E based on the input signal from the start button 227. For example, in the first self-optology program, as the examination items for checking the refractive power of the subject's eye, a spherical examination, an astigmatism axis examination, a cylindrical examination, and a visual acuity examination are performed. For example, the control unit 60 changes the correction value of the subject's eye, the type of examination target presented to the subject's eye E, the visual acuity value, etc., and performs these examinations in sequence.

[0103] <Spherical surface inspection (step S1)>

[0104] In the present embodiment, a red-green test is performed to adjust the spherical correction value of the eye to be examined. In the red-green test, it can be determined whether the state of the eye to be examined corrected with the desired spherical correction value corresponds to the state of myopia, emmetropia, or hyperopia. For example, if the visual mark that can be clearly visually confirmed is red, it is determined to be in the state of myopia; if the visual mark that can be clearly visually confirmed is green, it is determined to be in the state of hyperopia; if they are the same degree, it is determined to be in the state of emmetropia. It should be noted that, for example, in the state of hyperopia, it is considered to be overcorrected, and the spherical correction value is reduced until it becomes an emmetropia (or myopia) state.

[0105] When the red-green test starts, the control unit 60 generates voice guidance from the speaker 3 indicating the operation method of the controller 20 for the subject in the red-green test. As an example, the voice guidance may be as follows: if the red sight mark or the green sight mark that can be clearly visually confirmed is red, the answer lever 21 is lowered to the left; if the red sight mark or the green sight mark that can be clearly visually confirmed is green, the answer lever 21 is lowered to the right; if the sight marks are the same, the answer button 22 is pressed.

[0106] Next, the control unit 60 causes the test to proceed and causes the red and green sight marks to be displayed on the display 31. For example, the red color of the red and green sight marks is displayed on the left side, and the green color of the red and green sight marks is displayed on the right side. In addition, the control unit 60 generates a voice guidance to inquire about the color of the sight mark that the subject can clearly visually confirm. The subject confirms the sight mark, and causes the answer lever 21 to fall to either the left or right direction, or presses the answer button 22.

[0107] When the control unit 60 receives a response signal from the answer rod 21 based on the subject's selection of either the red or green sight mark, the control unit 60 increases or decreases the spherical power by one level according to the tilting direction of the answer rod 21. In addition, the control unit 60 again generates a voice guidance for inquiring about the color of the sight mark. For example, the control unit 60 repeatedly performs such control to automatically perform the examination.

[0108] For example, the control unit 60 ends the red-green test when receiving a response signal from the answer button 22 based on the subject judging the red and green sight marks to be of the same degree. It should be noted that the spherical correction value for correcting the subject's eye at the end time of the examination is set to the spherical correction value at the start time of the vision test.

[0109] <Astigmatism axis inspection (step S2)>

[0110] Next, in this embodiment, a cross-cylinder test is performed to adjust the astigmatism axis angle of the eye to be inspected. Here, it is possible to determine whether the astigmatism axis angle of the eye to be inspected is consistent with the desired astigmatism axis angle of the eye to be inspected. For example, if there is a difference in the visual effects of the two dot matrix sight marks, it is determined that the angles are inconsistent, and if the visual effects of the two dot matrix sight marks are the same, it is determined that the angles are consistent.

[0111] When the cross-cylinder test starts, the control unit 60 generates voice guidance from the speaker 3 indicating the operation method of the controller 20 for the subject in the cross-cylinder test. As an example, the voice guidance to the following meaning is generated: tilt the answer rod 21 in the direction of the dot matrix sight mark that can be clearly visually confirmed, and if the degree is the same, press the answer button 22. The control unit 60 repeatedly changes the astigmatism axis angle until a response signal is received from the answer button 22, and ends the cross-cylinder test when a response signal is received from the answer button 22. It should be noted that the astigmatism axis angle of the eye to be tested is corrected at the end time point of the examination and is set to the astigmatism axis angle at the start time point of the vision test.

[0112] <Cylinder Inspection (Step S3)>

[0113] Next, in the present embodiment, the cross-cylinder test is performed again to adjust the cylindrical correction value for correcting the eye to be inspected. Here, it is possible to determine whether the state of the eye to be inspected corrected with the desired cylindrical power is appropriate. For example, if there is a difference in the visual effects of the two dot matrix sight marks, it is considered inappropriate, and if the visual effects of the two dot matrix sight marks are of the same degree, it is considered appropriate. The control unit 60 similarly generates voice guidance, repeatedly changes the cylindrical correction value until a response signal is received from the answer button 22, and ends the cross-cylinder test when a response signal is received from the answer button 22. It should be noted that the cylindrical correction value for correcting the eye to be inspected at the end time point of the examination is set to the cylindrical correction value at the start time point of the vision examination.

[0114] <Spherical surface inspection (step S4)>

[0115] Next, in this embodiment, the red-green test is performed again to adjust the spherical correction value of the eye to be examined. Here, it is confirmed whether the adjustment of the eye to be examined is effective. As an example, the spherical correction value is the same at the end of step S1 and the beginning of step S4, but when the adjustment is effective, the visual effect of the red and green sight mark will change. It should be noted that the red-green test in step S4 is basically the same as the red-green test in step S1, so the description is omitted.

[0116] <Vision Test (Step S5)>

[0117] Next, in a state where the subject's eye is corrected with the predetermined correction value adjusted in steps S1 to S4 , a corrected visual acuity test (VA test) is performed to obtain the maximum visual acuity value.

[0118] When the corrected vision test starts, the control unit 60 generates voice guidance from the speaker 3 indicating the operation method of the controller 20 for the subject in the corrected vision test. As an example, the voice guidance is as follows: Tilt the answer lever 21 in accordance with the direction of the notch of the Landau ring mark, and press the answer button 22 if the direction of the notch is unknown. When the control unit 60 receives a response signal from the answer lever 21 based on the direction of the notch selected by the subject, the control unit 60 increases or decreases the visual acuity value by one level according to the tilting direction of the answer lever 21. The control unit 60 repeatedly changes the direction of the notch until the response signal from the answer button 22 is received, and ends the corrected vision test when the response signal from the answer button 22 is received. For example, the visual acuity value of the Landau ring mark to which the subject last correctly answers is obtained as the highest visual acuity value.

[0119] <Initialization>

[0120] In the present embodiment, in the self-optometry using the subjective optometry device 100, each of the above-mentioned steps S1 to S4 is performed on the left eye after being performed on the right eye. The control unit 60 outputs the test results of the right eye and the left eye (for example, the measured values ​​of the spherical correction value, the cylindrical correction value, the astigmatism axis angle, etc.). For example, the control unit 60 can display the measured values ​​on the self-optometry auxiliary screen 200, or print them out, or output them to the outside of the device through wireless communication or wired communication.

[0121] The examiner confirms the examination result of the subject's eye and presses a not-shown examination end button for ending the self-optometry of the subject's eye. The control unit 60 clears the examination result displayed on the self-optometry assistance screen 200 according to the input signal from the examination end button. At this point, the initialization of the subjective optometry device 100 is completed.

[0122] Thus, in this embodiment, when the first self-eye examination program is set, the examination items (spherical examination, astigmatism axis examination, cylindrical examination, and visual acuity examination) for examining the refractive power of the eye to be examined are automatically performed. For example, by setting the first self-eye examination program and performing the prescribed limited examination items, it is easy to handle the examination even when the examiner has little experience. In addition, the time for self-eye examination is shortened, so the examination can be smoothly performed in consideration of the crowded conditions of the facility or store where the device is installed.

[0123] <Subjective examination based on the second self-refraction procedure>

[0124] In this embodiment, the first self-eye test program is initially set, but it can be switched to the second self-eye test program according to the type of glasses desired by the subject and various conditions when the subject's eyes are examined. For example, in the case of so-called custom lenses that support fine adjustment of the subject's line of sight and visual effects, or in the case where facilities and stores are not crowded and can provide more thoughtful responses, the self-eye test program can be appropriately switched.

[0125] Next, a subjective inspection according to the process of the second self-optology program will be described. First, the examiner switches the self-optology program using the self-optology assistance screen displayed on the monitor 12 of the examiner controller 10 .

[0126] Figure 7 This is an example of the self-optology assistance screen 200 when the second self-optology program is set. For example, the examiner changes the setting from the first self-optology program to the second self-optology program by pressing the self-optology program switching button 224. The control unit 60 changes the overlapping display of the self-optology program name at the self-optology program switching button 224. In addition, the control unit 60 calls the second self-optology program from the memory 70 and applies it.

[0127] In addition, the examiner uses the self-refraction auxiliary screen 200 to prepare for the subjective examination according to the process of the second self-refraction procedure (for example, setting the initial value of the correction of the subject's eye E), and starts the self-refraction. For example, in the second self-refraction procedure, in addition to the examination items for checking the refractive power of the subject's eye, a binocular accommodation balance check for checking the balance of the accommodation of the subject's eye is also performed as an examination item for checking the binocular visual function of the subject's eye. For example, the control unit 60 changes the correction value of the subject's eye, the type of examination target presented to the subject's eye E, the visual acuity value, etc., and performs these examinations in sequence.

[0128] For example, similar to the first self-eye examination procedure, in the second self-eye examination procedure, the spherical surface test (step S1) to the visual acuity test (step S5) are also performed in sequence (it should be noted that their descriptions are omitted). For example, if the spherical surface correction value, cylindrical surface correction value, astigmatism axis angle, etc. are obtained for the right eye and the left eye, the process is transferred to the binocular accommodation balance test.

[0129] <Binocular Adjustment Balance Check (Step S6)>

[0130] In this embodiment, the polarized red-green test is performed to adjust the balance of the visual effects of the right eye and the left eye. In the polarized red-green test, it can be determined whether the adjustment of the right eye and the left eye is equal. For example, if there is a difference between the visual effects of the upper red and green optotypes and the lower red and green optotypes in the polarized red-green optotypes, it is determined that the balance is not achieved.

[0131] FIG. 8 is a diagram illustrating a polarized red-green vision target 80 . Fig. 8A Shows the visual effect in both eyes. Figure 8B The visual effect in the left eye is shown. Figure 8C The visual effect in the right eye is shown. For example, the polarized red-green sight mark 80 is composed of a polarized red-green sight mark 83 for the left eye (hereinafter, referred to as the left polarized R / G sight mark 83), a polarized red-green sight mark 81 for the right eye (hereinafter, referred to as the right polarized R / G sight mark 81) and a fusion sight mark 85. For example, the left polarized R / G sight mark 83 includes a red sight mark 83R arranged on the left side and a green sight mark 83G arranged on the right side. For example, the right polarized R / G sight mark 81 includes a red sight mark 81R arranged on the left side and a green sight mark 81G arranged on the right side. For example, the fusion sight mark 85 is arranged between the right polarized R / G sight mark 81 and the left polarized R / G sight mark 83.

[0132] When the polarized red-green test starts, the control unit 60 generates voice guidance from the speaker 3 indicating the operation method of the controller 20 for the subject in the polarized red-green test. As an example, the following voice guidance can be generated: when the upper layer (right eye) can clearly visually confirm the green sight mark and the lower layer (left eye) can clearly visually confirm the red sight mark, the answer rod 21 is lowered to the left. In addition, the following voice guidance can be generated: when the upper layer can clearly visually confirm the red sight mark and the lower layer can clearly visually confirm the green sight mark, the answer rod 21 is lowered to the right. In addition, the following voice guidance can be generated: when the green sight marks of the upper and lower layers can be clearly visually confirmed, when the red sight marks of the upper and lower layers can be clearly visually confirmed, and when all the sight marks of the upper and lower layers can be visually confirmed to the same extent, press the answer button 22.

[0133] Next, the control unit 60 causes the test to proceed and displays the polarized red and green sight marks on the display 31. In addition, the control unit 60 arranges the polarized lenses 30L and 30R in the test window 43 of the eye refractive power measurement unit 40. When the control unit 60 receives a response signal from the answer lever 21 of the subject, the control unit 60 increases or decreases the spherical correction value by one level according to the tilting direction of the answer lever 21. In addition, for example, the control unit 60 repeatedly adjusts the spherical correction value until a response signal is received from the answer button 22, and ends the polarized red and green test when a response signal is received from the answer button 22.

[0134] When the binocular accommodation balance check of the subject's eye E is completed, the control unit 60 outputs the check results of the spherical correction value, cylindrical correction value, astigmatism axis angle, etc. of the subject's eye E. In addition, the control unit 60 clears the check results displayed on the self-optometry assistance screen 200 according to an input signal from a check end button (not shown) based on the operation of the examiner, so that the initialization is completed.

[0135] Thus, in this embodiment, when the second self-optometry program is set, after the examination items (spherical examination, astigmatism axis examination, cylinder examination and visual acuity examination) for examining the refractive power of the eye to be examined, the binocular visual function examination of the eye to be examined E is automatically performed. Of course, the binocular visual function examination may also be an examination item different from the binocular accommodation balance test described above, and an examination item different from the binocular accommodation balance test may also be performed in addition to the binocular accommodation balance test. Thus, a more detailed examination result of the eye to be examined can be obtained through self-optometry.

[0136] <Second Embodiment>

[0137] A second embodiment of the subjective optometry system of the present embodiment is described. Here, a case where the self-optometry program applied to the subjective optometry device 100 is automatically switched by setting a plan corresponding to a prescribed period is given as an example. It should be noted that the same structure as the first embodiment (for example, the appearance of the device, the light projection optical system, the control unit, etc.) is the same as the first embodiment, so the detailed description is omitted.

[0138] Fig. 9 This is an example of the self-optometry assistance screen in the second embodiment. A plan setting button 228 may also be provided in the self-optometry assistance screen 200. For example, the plan setting button 228 is a button for displaying a plan setting screen. For example, the plan setting screen is a screen for setting a self-optometry program based on calendar information.

[0139] Fig.10It is an example of the plan setting screen 300. For example, the plan setting screen 300 is provided with a calendar screen 310, a month switching button 311, a date button 312, a day-of-the-week switching button 313, a weekday switching button 314, a screen switching button 320, etc. For example, the calendar screen 310 is a screen for setting and confirming the self-eye test program for each date. For example, the month switching button 311 is a button for switching the calendar (month) of the calendar screen 310. For example, the date button 312 is a button for setting the self-eye test program for the desired date. For example, the day-of-the-week switching button 313 is a button for collectively setting the self-eye test program in units of days of the week. For example, the weekday switching button 314 is a button for collectively setting the self-eye test program in units of weeks. For example, the screen switching button 320 is a button for returning to the self-eye test assistance screen 200 (refer to Fig. 9 ) button.

[0140] <Control Action>

[0141] The control action in the second embodiment of the active optometry device 100 having the above structure is described. The active optometry device 100 of this embodiment automatically switches between the first self-optometry program and the second self-optometry program according to the optometry plan set in advance. For example, in particular, by setting the optometry plan in accordance with the facility where the device is installed, the operating conditions of the store (crowded time period, schedule, etc.), etc., self-optometry of the subject's eye can be smoothly performed.

[0142] <Setting up the optometry plan>

[0143] First, the examiner sets a corresponding optometry plan for the first self-optology program and the second self-optology program for a specified period. For example, the examiner operates the examiner controller 10 and presses the plan setting button 228 of the self-optology auxiliary screen 200. The control unit 60 displays the plan setting screen 300 based on the input signal from the plan setting button 228. In addition, for example, the examiner presses any one of the date button 312, the day of the week switch button 313, and the Monday switch button 314 from the calendar screen 310 of the plan setting screen 300. Here, the case of selecting the date button 312 is taken as an example. The control unit 60 displays the self-optology program selection screen based on the input signal from the date button 312. For example, the self-optology program selection screen is a screen for setting a desired self-optology program for the date specified by the date button 312.

[0144] Fig.11This is an example of the self-optometric program selection screen 400. For example, the self-optometric program selection screen 400 may be provided with a self-optometric program selection column 410, a self-optometric program display column 420, etc. For example, the self-optometric program selection column 410 has a radio button for selecting any one of the first self-optometric program and the second self-optometric program, etc. For example, the self-optometric program display column 420 displays the order of performing the inspection items for the self-optometric program selected by the radio button of the self-optometric program selection column 410.

[0145] For example, the examiner uses the self-optometry program display column 420 to confirm the examination content of each self-optometry program, and uses the radio button of the self-optometry program selection column 410 to select a desired self-optometry program. For example, the control unit 60 displays the plan setting screen 300 (see Fig.10 ) is displayed so that the examiner can identify the symbol of the selected self-optology program (in this embodiment, it is set to "A" in the case of the first self-optology program and "B" in the case of the second self-optology program) and is superimposed on the date button 312.

[0146] For example, the examiner operates the date buttons 312 one by one to set the first self-eye examination program and the second self-eye examination program for a period such as a week, a month, or half a year. It should be noted that, for example, each date button 312 may be pre-initialized with the first self-eye examination program "A", and the date button 312 may be used to select the second self-eye examination program "B" only for a specified date. In addition, for example, it may be configured to be able to copy the settings at the specified date button 312 to different dates, and it may be configured to be able to set multiple days in a centralized manner. In addition, for example, it may be possible to set the first self-eye examination program or the second self-eye examination program using a schedule or the like. In other words, it may be possible to set the time period for applying the first self-eye examination program or the second self-eye examination program. As an example, it may be possible to change the settings of the self-eye examination program in time units such as morning and afternoon.

[0147] For example, the examiner presses the screen switching button 320 to return to the self-optometry support screen 200. The control unit 60 associates the date of the date button 312 with the self-optometry program selected by the examiner and stores them in the memory 70 in accordance with the operation signal from the screen switching button 320. Thus, for example, an optometry plan is created.

[0148] <Switching of self-refraction program>

[0149] The control unit 60 uses a timing mechanism (e.g., a calendar timer, etc.) not shown in the figure that is provided by the subjective optometry device 100 to obtain the current date and time. In addition, if it is a specified time to change the self-optometry program (e.g., 0:00:00 a.m., etc.), the control unit 60 calls out the specified self-optometry program from the memory 70 according to the optometry plan and applies it, and automatically switches the self-optometry program. For example, the control unit 60 can overwrite the setting of the specified self-optometry program only at a specified time on the day when the first self-optometry program and the second self-optometry program are switched on the optometry plan. In addition, for example, the control unit 60 can also cancel the setting of the current self-optometry program at a specified time every day, regardless of whether the first self-optometry program and the second self-optometry program are switched on the optometry plan, and reflect the setting of the specified self-optometry program.

[0150] Thus, in this embodiment, it is possible to pre-set each self-eye examination procedure to establish a corresponding eye examination plan. For example, by understanding the work shifts of the inspector, the operating conditions of the facility, the crowded time period, etc. and setting an eye examination plan that takes them into consideration, it is possible to easily set a suitable self-eye examination procedure and smoothly conduct the examination.

[0151] As described above, for example, the subjective optometry system of this embodiment includes: a sight mark presenting unit that presents an inspection sight mark to the eye to be inspected; a correction unit that changes the optical characteristics of the sight mark light beam emitted from the sight mark presenting unit; and a self-optometry program setting unit that sets any one of a first self-optometry program and a second self-optometry program, wherein the first self-optometry program automatically performs a plurality of inspection items for the eye to be inspected based on an answer input by the examinee, and the second self-optometry program automatically performs a plurality of inspection items for the eye to be inspected based on an answer input by the examinee, and the inspection conditions are different from those of the first self-optometry program, and the subjective optometry system controls at least one of the sight mark presenting unit and the correction unit based on the first self-optometry program or the second self-optometry program set by the self-optometry program setting unit, so that optometry according to the process of the self-optometry program is performed. With such a structure, it is possible to easily apply a program that matches the type of glasses, inspection conditions, operating conditions, etc., and smoothly perform the inspection.

[0152] In addition, for example, in the subjective optometry system described in the present embodiment, at least one of the plurality of inspection items is different as an inspection condition in the first self-optometry program and the second self-optometry program. Thus, for example, by appropriately setting the first self-optometry program and the second self-optometry program and performing the program of the inspection items corresponding to the type of glasses desired by the examinee, the inspection condition of the examinee's eye, the facility where the device is installed, the operating condition of the store, etc., the inspection can be smoothly performed.

[0153] In addition, for example, in the subjective optometry system described in the present embodiment, the first self-optometry program includes an inspection item for checking the refractive power of the eye to be inspected as a plurality of inspection items, and the second self-optometry program includes an inspection item for checking the binocular vision function of the eye to be inspected as a plurality of inspection items in addition to the inspection item for checking the refractive power of the eye to be inspected. For example, the inspection item for checking the refractive power of the eye to be inspected is a general inspection item. Therefore, by setting the first self-optometry program, it is possible to efficiently cope with more subjects. In addition, for example, the inspection item for checking the binocular vision function of the eye to be inspected is an inspection item that is performed in situations where it is desired to understand the optical characteristics of the eye to be inspected. Therefore, by setting the second self-optometry program, it is possible to use the inspection results of the refractive power and visual function of the eye to be inspected to produce glasses that are more suitable for the eye to be inspected.

[0154] In addition, for example, the active optometry system of the present embodiment includes an optometry plan setting unit for setting an optometry plan corresponding to the first self-optometry program and the second self-optometry program for a prescribed period, and the self-optometry program setting unit switches and sets the first self-optometry program and the second self-optometry program based on the optometry plan set by the optometry plan setting unit. Thus, for example, an optometry plan corresponding to the operating conditions of a facility or store where the active optometry system is installed can be set, and since the self-optometry program is automatically switched every prescribed period, an inspection can be smoothly performed.

[0155] In addition, for example, the active optometry system of the present embodiment includes an operation unit for inputting an operation signal for setting at least one of the first self-optometry program and the second self-optometry program, and the optometry plan setting unit sets the optometry plan corresponding to the first self-optometry program and the second self-optometry program for a prescribed period based on the operation signal from the operation unit. For example, managers of facilities and stores that have installed the active optometry system or inspectors who use the active optometry system can set the most suitable optometry plan for each facility or store, and since the self-optometry program corresponding to the operating conditions is automatically applied, the inspection can be smoothly performed.

[0156] <Modification>

[0157] In the present embodiment, a structure in which a plurality of inspection items are different as inspection conditions of the first self-optometre procedure and the second self-optometre procedure is cited as an example for explanation, but it is not limited to this. For example, it may also be a structure in which different inspection sight marks are used in a plurality of inspection items as inspection conditions of the first self-optometre procedure and the second self-optometre procedure. For example, the first self-optometre procedure and the second self-optometre procedure may both be procedures that sequentially perform a spherical inspection and a visual acuity inspection. Of course, in the second self-optometre procedure, a binocular adjustment balance inspection, an eye position inspection, etc. may also be implemented. For example, in this case, it may be that the inspection sight marks used in the visual acuity inspection of the first self-optometre procedure and the visual acuity inspection of the second self-optometre procedure are different. As an example, it may be that the Landau ring sight mark or the rolling E sight mark is used differently. Similarly, different inspection sight marks may be set for the spherical inspection, the astigmatism axis inspection, and the cylindrical inspection of the first self-optometre procedure and the second self-optometre procedure. It should be noted that each self-optometre procedure does not necessarily need to set different inspection sight marks in all common inspection items.

[0158] In the subjective optometry system described in the present embodiment, in the first self-optometry program and the second self-optometry program, different inspection sight marks are used in the inspection items as inspection conditions. For example, in the inspection of the inspected eye, the type and representation of the inspection sight mark may be changed in accordance with the country or region where the subjective optometry system is installed, or the number and type of the inspection sight mark may be changed according to the inspection condition of the inspected eye. By pre-setting a plurality of self-optometry programs with different inspection sight marks as in the present embodiment, the self-optometry program can be switched as needed, and the inspection can be smoothly performed.

[0159] In this embodiment, a structure for manually setting any one of the first self-eye examination program and the second self-eye examination program is cited as an example for explanation, but it is not limited to this. In this embodiment, it is also possible to have a structure for automatically setting these self-eye examination programs. For example, in this case, information such as a reservation system that can confirm the congestion status of facilities and stores can be used. In addition, for example, in this case, subject information (subject ID, etc.) can also be used.

[0160] For example, in the case of utilizing information from a reservation system, etc., the control unit 60 can switch the self-eye examination program based on whether the number of subjects to be examined exceeds a certain number. For example, the control unit 60 can set a first self-eye examination program when the number of subjects registered in the reservation system exceeds a certain number. In the present embodiment, by applying the first self-eye examination program, only general refractive examination items are implemented. Therefore, in a situation where the number of subjects waiting is large, self-eye examination can be carried out efficiently. In addition, for example, the control unit 60 can set a second self-eye examination program when the number of subjects registered in the reservation system is less than a certain number. In the present embodiment, by applying the second self-eye examination program, binocular adjustment balance examination and the like are also implemented. Therefore, in a situation where the number of subjects waiting is small, more detailed examination results of the subject's eye can be obtained.

[0161] For example, when using the subject information, the control unit 60 can switch the self-eye test program based on data associated with the subject information, such as the type of glasses made last time, the result of the last examination, the presence or absence of a disease, etc. For example, the control unit 60 can set the second self-eye test program when the subject information includes a history of performing a binocular accommodation balance test in the last examination.

[0162] In this embodiment, a structure in which the inspection conditions of the first self-eye examination program and the second self-eye examination program are pre-set and the inspection is performed according to the specified inspection items is cited as an example for explanation, but the present invention is not limited to this. For example, it is also possible to configure the inspection conditions of at least one of the first self-eye examination program and the second self-eye examination program to be able to be changed in advance.

[0163] Fig.12 This is an example of a self-optology support screen 200 for editing the inspection conditions of the self-optology program. For example, a self-optology program edit button 229 may be provided on the self-optology support screen 200. For example, the self-optology program edit button 229 is a button for displaying the self-optology program edit screen.

[0164] Fig.13 500. For example, the self-eye test program selection screen 500 includes a self-eye test program selection button 501, a self-eye test program addition button 502, and a screen switching button 503. For example, the self-eye test program selection button 501 is a button for editing a self-eye test program. For example, the self-eye test program addition button 502 is a button for additionally registering a self-eye test program. For example, the screen switching button 503 is a button for returning to the self-eye test assistance screen 200 (see Fig.12 ) button.

[0165] For example, when the examiner presses the self-optology program selection button 501 of the self-optology program selection screen 500, the control unit 60 displays the self-optology program editing screen based on an input signal from the self-optology program selection button 501. For example, the self-optology program editing screen is a screen for editing the contents of the self-optology program.

[0166] Fig.14 This is an example of a self-optometrist program editing screen 600. For example, the self-optometrist program editing screen 600 is provided with a self-optometrist program execution order bar 610, an examination item selection bar 620, an examination item editing bar 630, a screen switching button 640, and the like. For example, the self-optometrist program execution order bar 610 can change the execution order of the examination items of the self-optometrist program, and add or delete examination items. For example, the examination item selection bar 620 displays the examination items that can be added to the self-optometrist program. For example, the examination item editing bar 630 changes the examination sight mark used in the examination item selected by the examination item selection bar 620. For example, the voice guidance selection bar 632 selects the content of the voice guidance for the examination item selected in the examination item selection bar 620. For example, the screen switching button 640 is to return to the self-optometrist program selection screen 500 (refer to Fig.13 ) button.

[0167] For example, the examiner can change whether to implement the inspection items included in at least one of the first self-optology program and the second self-optology program from the self-optology assistance screen 200. As an example, here, the case of adding a stereoscopic vision inspection to the inspection items of the second self-optology program is taken as an example. The examiner presses the self-optology program edit button 229 of the self-optology assistance screen 200. The control unit 60 displays the self-optology program selection screen 500 based on the input signal from the self-optology program edit button 229. In addition, the examiner presses the self-optology program selection button 501 of the self-optology program selection screen 500. For example, press the button corresponding to the second self-optology program. The control unit 60 displays the self-optology program edit screen 600 based on the input signal from the self-optology program selection button 501.

[0168] The examiner drags and drops the stereoscopic vision test selected from the list of test items displayed in the test item selection column 620 to any position in the order of the test items in the second self-optology program displayed in the self-optology program order column 610. For example, the stereoscopic vision test is dragged and dropped to the next position of the binocular accommodation balance test. When setting the second self-optology program, the control unit 60 adds the stereoscopic vision test to the order of the second self-optology program in a manner that the stereoscopic vision test is performed in addition to the aforementioned spherical test to binocular accommodation balance test. For example, in this way, it is possible to change whether to implement the test items included in each self-optology program.

[0169] In addition, for example, the examiner can change the type of the inspection target used in the inspection items included in at least one of the first self-optology program and the second self-optology program from the self-optology auxiliary screen 200. As an example, here, the case of changing the type of the inspection target used in the corrected visual acuity test (VA test) of the second self-optology program is given as an example. The examiner operates the self-optology program edit button 229 and the self-optology program select button 501 to call up the self-optology program edit screen 600.

[0170] The examiner selects a corrected visual acuity test (VA test) from the list of examination items displayed in the examination item selection column 620. The control unit 60 displays the type of examination target set for the corrected visual acuity test in the examination item editing column 630 based on the input signal from the examination item selection column 620. For example, as the type of examination target, either the Landau ring target 631a or the rolling E target 631b can be set, and the column corresponding to the examination target selected by the examiner can also be highlighted. The control unit 60 reflects the setting of the second self-optology program in the manner of displaying the Landau ring target in the corrected visual acuity test. For example, in this way, the type of examination target used in the examination items included in the self-optology program can be changed.

[0171] It should be noted that the examiner can also add a self-optology program different from the first self-optology program and the second self-optology program using the self-optology program addition button 502. In addition, the examiner can also change the content of the voice guidance for the inspection item selected in the inspection item selection column 620 from the voice guidance selection column 632 of the self-optology program editing screen 600. For example, it may be possible to change at least one of the message read out by the voice guidance and the frequency of repeating the voice guidance.

[0172] In this way, the subjective optometry system of the present embodiment has a setting change unit for changing at least any one of the inspection conditions of the first self-optometry program and the inspection conditions of the second self-optometry program. For example, the inspection conditions of the first self-optometry program and the second self-optometry program pre-set in the subjective optometry system are sometimes not suitable for the subject. For example, in such a case, by changing (that is, rewriting) the inspection conditions of the self-optometry program in a manner that becomes the inspection conditions desired by the examiner before starting self-optometry for the subject's eye, the inspection can be smoothly carried out under the desired inspection conditions.

[0173] In the present embodiment, a structure for manually setting an optometry plan that establishes a corresponding optometry plan for either the first self-optometry program or the second self-optometry program and a prescribed period is cited as an example for explanation, but is not limited to this. In the present embodiment, a structure for automatically setting such an optometry plan may also be possible. For example, a structure for automatically setting an optometry plan may also be possible by receiving an operation signal from a management medium (e.g., a computer, a terminal device, etc.) that manages the subjective optometry system. It should be noted that in this case, it is also possible to send an optometry plan from one management medium to multiple subjective optometry devices, and change the settings of multiple subjective optometry devices at the same time to unify the optometry plan.

[0174] Fig.15 It is a diagram of multiple subjective optometry devices connected to a network via a terminal device. For example, the terminal device 700 can be a tablet PC, a notebook PC, a smart phone, a desktop PC, a main subjective optometry device, etc. For example, the terminal device 700 is connected to multiple subjective optometry devices in a manner that allows communication. For example, the terminal device 700 is connected to multiple subjective optometry devices through a network through at least one of wireless communication and wired communication. For example, the examiner uses the terminal device 700 to make an optometry plan, and saves the information of the optometry plan (CSV file, etc.) in a shared folder 710 on the network. For example, the control unit of each subjective optometry device obtains the information of the optometry plan saved in the shared folder 710 on the network at startup, and based on this, any one of the first self-optometry program and the second self-optometry program corresponds to the date, etc. In this way, the optometry plan can be automatically set. Therefore, the trouble of the examiner can be reduced. In addition, in this way, the optometry plan is unified in multiple subjective optometry devices.

[0175] It should be noted that the information of the optometry plan stored by the terminal device 700 may be set with identification information for associating at least one of the multiple subjective optometry devices. For example, the identification information (for example, identification symbol, identification number, etc.) inherent to each subjective optometry device may be stored in association in the optometry plan information (CSV file, etc.). In this case, the control unit of each subjective optometry device can set a different optometry plan for each subjective optometry device by accessing the shared folder 710 and reading the optometry plan that matches the inherent identification number.

[0176] In the above description, the terminal device 700 and the network connection are used to automatically set the optometry plan in the subjective optometry device, but the optometry plan can also be set using an external storage medium. For example, the optometry plan information can also be stored in a USB memory, an SD card, etc., and the information can be read by each subjective optometry device. In addition, in the above description, the first self-optometry program and the second self-optometry program are set to establish a corresponding optometry plan from the terminal device 700, but the inspection conditions of at least one of the first self-optometry program and the second self-optometry program can also be set. In other words, the inspection items and inspection sight marks of each self-optometry program can also be changed and reflected in each device.

[0177] In the present embodiment, a structure in which the setting is automatically switched based on the establishment of a corresponding optometry plan for the first self-optometry program or the second self-optometry program and a prescribed period is used as an example for explanation, but the present invention is not limited thereto. For example, it may be configured such that: even if the first self-optometry program is set based on the optometry plan, the second self-optometry program is temporarily set, and the inspection items included in the second self-optometry program are performed in sequence. In addition, for example, it may be configured such that: even if the second self-optometry program is set based on the optometry plan, the first self-optometry program is temporarily set, and the inspection items included in the first self-optometry program are performed in sequence.

[0178] For example, the examiner presses the self-optometry assistance screen 200 (see Figure 7 ) can temporarily change the self-optology program. For example, when a first self-optology program is set according to the optometry plan, but it is determined that the second self-optology program should be used for the next examinee, the examiner can press the self-optology program switching button 224 to set the second self-optology program. The control unit 60 switches the setting to a second self-optology program that is different from the current first self-optology program based on the input signal from the optometry program switching button 224. In addition, if the examination based on the temporarily set second self-optology program is completed and the examination result is cleared, the control unit 60 sets the first self-optology program again. As a result, even if the examinee is not suitable for the current self-optology program, the self-optology program can be easily changed before the examination of the examinee, so that the examination can be carried out smoothly.
